AN AROMATIC HETEROCYCLIC COMPOUND, AN ORGANIC LIGHT EMITTING DIODE COMPRISING AN ORGANIC LAYER COMPRISING THE SAME AND AN METHOD FOR PREPARING THE ORGANIC LIGHT EMITTING DIODE

摘要

An aromatic heterocyclic compound is provided to ensure excellent light-emitting property, and to impart low driving voltage, high brightness, high efficiency, high purity and long lifespan to an organic light-emitting device. An aromatic heterocyclic compound has a structure represented by chemical formula 1. In chemical formula 1, A is substituted or unsubstituted benzo[k]fluoranthene or substituted or unsubstituted chrysene; Ar1 is substituted or unsubstituted C5-C12 arylene group; n is an integer of 0-6; Ar2 is a terminal group represented by chemical formula 2; m is an integer of 1-6; k is an integer of 1-4. In chemical formula 2, X1 is N(R4), S, and Se or Te; X2 and X3 are independently C(R5) or N; one of R1-R5 is a linkable site with A or Ar1 of the chemical formula 1 and the rest excluding a linkable site with A or Ar1 is hydrogen, halogen, cyano group, nitro group, hydroxyl group, substituted or unsubstituted C1-C20 alkyl group, substituted or unsubstituted C2-C20 alkenyl group, substituted or unsubstituted C2-C20 alkynyl group, substituted or unsubstituted C5-C20 cycloalkyl group, substituted or unsubstituted C5-C20 cycloalkenyl group, substituted or unsubstituted C5-C20 aryl, substituted or unsubstituted C2-C30 heteroaryl radical or - N(Z1)(Z2), wherein Z1 and Z2 are independently hydrogen, substituted or unsubstituted C1-C20 alkyl group or substituted or unsubstituted C5-C20 aryl group.
